In a hand brake mechanism, a brake shaft, a sleeve on the shaft, a step having a socket adapted to receive the foot of the brake shaft, and bendable lugs adapted to hold the sleeve and the shaft in position in relation to said step When bent about the sleeve.

4. In hand brake mechanism, a brake shaft and a step therefor, a sleeve rotatably connected with shaft, and bendable means integral with said step adapted to hold the sleeve and the shaft in position in relation to said step.

5. In a hand brake mechanism, a brake shaft, a sleeve mounted on said brake shaft, and a step having a socket for the foot of the brake shaft, and lugs adapted to be bent around the brake snaft sleeve to hold the sleeve and the shaft in place in relation to the said step.

6. In a hand brake mechanism, a brake shaft, a sleeve mounted thereon and adapted to rotate With said shaft and forming a drum for the brake chain, a iJ-shaped step having on its base a socket for the shaft, and across. its upper portion a bearing member integral therewith and adapted to be bent about said sleeve.

7. In a hand brake mechanism, a brake shaft rectangular in cross-section, a sleeve mounted thereon and adapted to rotate-with said shaft and forming a drum for the brake chain, a U-shaped step having on its base a socket for the shaft, and across its upper portion a bearing member integral therewith and adapted to be bent about said sleeve.

8. In a hand brake mechanism, a brake shaft in combination with a brake shaft step, said step comprising a U-shaped member having a socket in its base for the shaft and a plate for attachment to the car, said plate having an outwardly extending portion and lagsv thereon adapted to take about the shaft,

9. In hand brake mechanism, an integral ,ception of a shaft rectangular in cross secnon in one portion and round in cross section in another portion, the said shaft being apertnred for insertion of a retaining n below the sleeve. WALTER E. CGFFIN.
